MAPPING

Map Requirments: Basic Features 1. TITLE (usually, area displayed and the topic/purpose 2. LEGEND (explains the meaning of the symbols and colours) 3. SCALE (compares the distance between points on the map with the actual distance between those points, allowing the reader to measure distance and calculate area) Large-scale maps show a large amount of detail in a small area (1: and 1: or less are considered large-scale maps). 1: means that 1cm on the map represents cm/500m on the earth’s surface. Small-scale maps show a small amount of detail of a large area (1: and 1: or more are considered small-scale maps.

4. DATE OF PUBLICATION (indicates if the information is recent) 5. DIRECTION (represented in two ways: 1) by direction or “north” arrow/symbol, or 2) by the use of latitude and longitude lines 6. BORDERS (set the map apart from other information)

Sample #1 Feature: Legend: Permafrost and Ground Ice Conditions Colours show the permafrost zones

Sample #2 Feature: Legend: Relief – height of the surface of the land Colours show the height of the land Points A B A B 300 – 400 m 2000 – 3000 m

Topographic Maps – is a detailed map that shows both physical and human features.

Contour Lines – thin brown lines that trace the surface elevation, show how high the land is above sea level. Top ViewBottom View

Secrets in the Lines A - Where the slopes are steeper, the contour lines are closer together B - Where the slopes are gentler, the contours lines are further apart A B

Contour Interval Contour interval – this is the distance between each contour line. It remains the same for the whole map. Spot Height – this is the exact height of the land at that point only. The top left shows a spot height. (14) · 14

Which Way Do Rivers Flow Contours can show you the direction that rivers flow. The V shaped contours point up the valley. Rivers flow down valleys.
